IMPROVEMENT [N VENTILATORS.

Specification fo 'mingpart of Letters Patent No. 47.413, dated April 25, 1865.

To aZZ whom it may concern:

Be it known that I, HENRY A. GOUGE, of Brooklyn, Kings county, and State of New York, have invented a new and Improved Ventilating-Light and I hereby declare that the following is a t'nll, clear, and exact description thereof', reference being had to the aecompanying drawings, making a part of this speciication, and the letters ot' reference marked thereon, in which the same letter represents the same thing in each figure. i

Figure lisa vertical cross section Fig. 2, a representation of the mode ot application to an apartment.

The object of my invention is to promote the ventilation of any apartment by creating a current outside of it, into which current the impure air of the apartmentis fed and carried oii by it, the same contrivance also lighting the apartment without heating it or risk of fire.

.A represents a small chamber containing the light outside the apartment to be ventilated and lighted; B, the Ventilating-flue; C, the metal radiating-flue from chamber A l), the protectingvcap; E, the ventilator-escape; F, the light; G, the base of the lighted chamber perforated for the admission of air to promote combustion; H, the glass door of the chamber; I, the wall of the apartment to be ventilated and lighted.

The operation is as follows Light F rarees and heats the air in chamber A, which rises on the exterior of cone D,through radiating metal flue O, thereby rarcfyiug the air in ventilating-tlue B, which rises and passes 01T."

Ventilator F being open, the current of heated air in lue B sucks in its passage by it the foul and heated air of the apartment, which escape by that communication.

Gone D divides the current of air and prevents the extinguishing of light F by the sudden closing of bank-vault or other tight-fitting doors, which would drive the air impetuously through ventilator F and down flue C into chamber A.

It will be obvious that this improvement may be applied in different ways to many usei C, and ventilator E, constructed and arranged substantially as and for the purposes` described.
